Abstract: 1,145,584. Transformers. TOKO K.K. 10 July, 1967 [14 July, 1966; 20 Dec., 1966 (2); 21 Dec., 1966], No. 31700/67. Heading H1T. A winding no which introduces distributed capacitance into the primary winding of a tuned transformer has one of its terminals, e.g. So, connected to a terminal of different potential, e.g. F 1 , on the primary coil n 1 , the wire of winding no being wound side-by-side or bifilarly with part of the length of the wire of the primary. To maintain the wires in side-byside relationship they are coated with a thermoplastic material, e.g. polystyrene resin or polyethylene resin, and pressed between heated rollers before winding, and they may be coated initially with a heat-resistant insulating material. Alternatively the wires may be bonded with adhesive. In further embodiments the terminals Fo and S 1  may be connected, tappings may be provided, and the secondary may also have a winding for introducing capacitance. The ratio of the number of turns in the primary n 1  to the number of turns of coil no may be 3 : 1. Coil no may also act as a secondary.

[Class 100 (ii).] Addressing-machines; tripping-arrangements. -In an addressing-machine, a circuit to an electromagnet controlling the impression directly, or through a relay, is influenced by means of one or more light-sensitive cells to which light is transmitted when control signals on the printing-device or on a separate control card in selecting position correspond with the adjustment of a selecting-device. The printing- devices may be either printing- plates or stencils. In one form, Figs. 1 and 2, adapted for printing-plates a provided with control perforations or recesses b, the selecting-device consists of a plate f provided with a row of perforations i corresponding to control positions and with a series of cover-slides k, whereby one or more of the perforations may be exposed. Each one of a series of mirrors l arranged above the plate f is adjusted into an angular position such that light passing through any perforation i is directed on to a photo-cell n. Light from a lamp c arranged beneath the plate a passes through the perforations b, then through a screen e, and is transmitted to the cell n if at least one corresponding perforation i is uncovered. The plate f is reciprocated by arms h so that a momentary exposure only is allowed ; alternatively, the plate f may be stationary and the light c switched on momentarily. In a modification adapted for group control, a cell is provided for each of a number of groups of control perforations, each cell controls a switch, and all the switches are arranged in series in the circuit of a control electro magnet ; byepass switches are provided so that any of the groups may be eliminated. In a further modification, Fig. 4, mirrors l are provided above'and below the plate a, and light from the lamp c can only reach the cell n when the plate a has a group of three perforations b allowing transmission of the light as shown. In another modification, the plate a is provided with tabs adapted to reflect light from a lamp arranged above the plate, on to a cell. The machine may be stopped at the end of a series by providing a special perforation in a printing-plate or in a control card to co-operate with a separate cell controlling a separate electromagnet.

IPC: C10G11/04
Filed: 1930-10-23
Abstract: <PICT:0363051/III/1> <PICT:0363051/III/2> Oils are cracked under low pressure by vapourizing them before or during passage through tubes heated to cracking temperature and filled with non-absorbent silica or siliceous material in a state of fine division, e.g. silver sand, powdered calcined flint or pure silica which may be mixed with mica dust or asbestos and acts as a turbulence agent in the path of the oils.  The latter are caused by air or vapour pressure to flow from a storage tank 1 through a charging pipe 2 to preheating and cracking tubes 9, 11 arranged in upper and lower compartments 10, 12 of a furnace B. The cracked products pass through evaporating and fractionating columns 5, 7 in which the crude oil may be preheated by passage through coils 5, 7 to a condenser 16.  The tubes 9, 11 in Fig. 2 are filled with comminuted siliceous material 14 contained between perforated screens 19 held in position by vitreous annular linings 18 fitting into enlarged end portions 11b of the tubes. The linings are maintained in position by springs 22 or by a clamping ring.  The siliceous material may be revivified by passing air through the tubes which may be made annular in form by employing one tube within another and packing the annular passage thus formed with the silica.

As applied to a motor-cycle, the hub 12 of the spring drum is screwed by. a left-hand thread on a standard hub 13, being locked thereon by a right-hand threaded nut (not shown), and the hub 11 of a sprocket 9 bears freely upon it. In the form shown, each short limb 4 of the springs 1, lying in the channel 2 of the drum, is extended, as shown at 6<1>, to lie against the long limb 6 of the adjacent spring. The shoulders 5 of the slots 3 are so curved that the springs are initially in contact with them. The springs 1 normally contact by their free ends with the curved vanes 7, but as the driving- torque increases, they roll further on the vanes until their stiffness is sufficient to transmit the load, or until, as shown, the drive becomes solid. The curvature of the vanes coincides with the natural flexure of the springs.

A device for controlling an oil burner in a combustion chamber 4 comprises a diaphragm 30 responsive to the difference in pressure across an air throttle 3 in the air supply conduit 7 to the combustion chamber 4 and adapted to control a piston valve 32, the piston of which is subjected to the pressure of air in a chamber 33 fed by the piston valve from a compressor 17. The chamber 33 has a small outlet 19 the air pressure in the chamber 33 is also conveyed to a float chamber 18 in which fuel oil is maintained at a constant level and the air forces the oil to the burner. The oil supply is controlled by a valve 12 and the air supply by a valve 2. The device maintains substantially constant the ratio of the difference in air pressure across the throttle 3 to the difference in oil pressure across the valve 12. The compressor 17 also supplies atomizing air to the burner. In a modification, Fig. 4, not shown, the piston is replaced by a diaphragm.

Title: Quaternary ammonium compounds
IPC: C08G59/50
Filed: 1958-10-14
Abstract: The invention comprises quaternary ammonium derivatives of polymeric fat acid amines and a process for the preparation thereof in which polymeric fat acid amines are quaternized by reaction with a quaternizing agent.  The amine starting materials may be obtained by reacting polymeric fat acids with ammonia, dehydrating the product to produce the corresponding nitrile and hydrogenating the latter to obtain the corresponding amine or by polymerization of suitable fatty nitriles, followed by hydrogenation of the polymeric nitrile.  The fatty acids from which the amines are derived should have sufficient unsaturation to form the polymeric material, i.e. in general, an iodine number of at least 120.  Suitable acids specified are those of soybean, linseed, tung, perilla, cottonseed, corn, sunflower, safflower, dehydrated castor oil and tall oil and such fatty acid mixtures may be enriched in linoleic acid by crystallization and/or distillation.  The fatty acids may be polymerized by heating or by the method of U.S.A.  Specification 2,793,219.  Among quaternary salt-forming substances specified are included such compounds as methyl bromide, ethyl iodide, n-propyl chloride, sec. butyl bromide, n-hexyl chloride, benzyl chloride, methyl sulphate, methylbenzenesulphonate and methyl p-toluenesulphonate. Solvents may be employed in the process, e.g. alcohols such as isopropyl and butyl alcohols and alcohol-hydrocarbon mixtures. The reaction may be carried out in the presence of a base, e.g. alkali metal- and alkaline earth metal hydroxides, carbonates and alkoxides.  Only partial quaternization occurs in the absence of added base and quaternary compounds having different substituents attached to nitrogen may be obtained.  A polymeric fat acid amine quaternary ammonium compound is obtained by reacting an amine, prepared by reacting polymeric fat acids containing a preponderance of di-linoleic acid with ammonia to form the corresponding nitrile and hydrogenating the latter, with methyl chloride in the presence of sodium hydroxide solution and isopropanol at elevated pressure and temperature.  The products are paper softening agents (see Group VIII).
